good job ! Flowers are wonderful. Can clearly see the touch of coerulea , I think more than sanderiana.
Rothschildiana is an amazing hybrid ... created 80 years ago !
well done Dounoharm !
Fantastic! I've been looking (in vain) for a Rothschildiana for the last couple of years. How tall is your plant? From what I can see in your pictures, your plant (vegetatively speaking) looks like it more resembles the coerulea parent than the sanderiana. Very nice.
